"to it known that I, FANIL A. Dneitnn, :1 citizen of the United Slates, residing in the city of Philadelphia, county of Philadelphia and Suite of Pennsylvania, have in vented certain lniprovein'ents in Couplings .i'or ,lhitlea'y Elements of which the following is it weeitientiou.

This invention is nu improved coupling for buttery elements whereby \he int-ts are more readily connected and disconnected, a close engagement automatically innintoined so that, the conduction of current is ininrot'ed, the parts are insulated in such nniiiner that. n metal envelop can be used in the cell, and the debtrueiion due to the electrochemical action is greatly reduced.

in the accompanying drawings, Figure 1 is a perspective View of 1: form of the coupling applied to an electrode with parts broken it my for the purpose of illustration; Fig. 2 is a plan View of a eeeond form thereof and a. portion of a cell to-whieh it is applied; Fig. 3 n perspective View of a third .t'orm with connecting parts; lug. -LL IS a plan View representing an upplmition oi -the construction t town in Fig. 3; and Fi 5i a perspeetire view of a further term with n section of plat connected thereto.

in the prei'e: 1 construction, the inv ntion eonsisto, stated broadly, of a downwardly tapered lug secured to the electrode and n holder with n. downwardly tapered eoe tet opening through :1 slot for receiving the lug and 2t portion of the electrode, the hnlde being secured to the enyelop.

Ass ltOfl/ll in Fig. l, the electrode 1 has secured thereto the downwardly layering hearing in the form of the lug and the holder 3 has therein a downwardly tapered 1 'liLl; +l, ltlttli 1 v trodes.

hearing in the form of the so reeeives the lug, and the slot 5 which reunihfi :1 portion of the plate tNi liU'tlll/I thereto. The holder is inclined in an insulating; Shoe (3 to prevent. its destruction with the electrode and lug. The insulating ensing for the holder further provides tor its use with it metal cell envelop by which the connector and electrode may he inechzsnie- :illy supported without being electrically eonneeted therewith.

As shown in Fig. several 0 reepeel 'i'e llll 'f-l 2 {ll-C oi with tnei supporttw :1 s1 holder lidvnig of Sf)"l(0l and elois 54' therein, the holder being inonsed in the insulating shoe 9. flhesiparts are supported h the metal lliti'lwii It) by means of. the :wrew ll, which pukethrough the conducting hair 12 separated h the insulation 12 from the envelop. the en= i'elep and the shoe into the holder, the atl'e.\ milking electrical its well no nieehzinimil connection between the hinder and the lmr hile being out of contact with the envelop. 'lhis holder is pro ided with the ICCUSFS 1;? which receives the end of the ncgutivc electrode let. As shown in Fig. 3, the electrode l3 has the downwardly tapered lug tt lornied thereon by hem ing or rolling an extension of the electrode. This lug and electrode :irc titted to the socket l? and the slot 18 of ii holder 19 which prtwidedwilli u projoo non 20 gn'oviding it downwardly taperingthe lltdtltjl'iil9, engaged to lrconnemiug her 522 as described, may he engaged within the insuhi lug envelop :23, through which and the conducting bar 24 pass a conducting; screw 25 into the conducting bar 2;

As SllOWlllIl Fig. 5, the electrode 26 hits :1 lug 27 ocnt'u from sheet metal and couneeted thereto 3y means of the extensions 538, and a plurality of sucheleeirtnles are supported by their engagements with 'mOClUFtS 29 and slots 30 in n holder 31, which has the angular extension 32 fOlZCOHHQCliOiI with n conduetor.

Preferably the lugs and the electrodes are made of the StllllG material, :is zinc, and the holders are made of conducting material eleetro-uegntive thereto in order that they slictll not suffer destruction with the elec- While only the holders shown in l and 2 are llltjitr'i'tlll in insulating shoes, it IS to he understood that the reuniiniug Forms may be so inc-used.
